Я нашел решение этой проблемы.
Существует способ создавать миграции программно вместо использования CLI.
После просмотра MigrationsScaffolderИсходный код Мне удалось изменить код в первой ссылке, чтобы удовлетворить мои потребности:
using (var db = new MyDbContext())
{
var reporter = new OperationReporter(
new OperationReportHandler(
m => Console.WriteLine(" error: " + m),
m => Console.WriteLine(" warn: " + m),
m => Console.WriteLine(" info: " + m),
m => Console.WriteLine("verbose: " + m)));
var designTimeServices = new ServiceCollection()
.AddSingleton(db.GetService<IHistoryRepository>())
.AddSingleton(db.GetService<IMigrationsIdGenerator>())
.AddSingleton(db.GetService<IMigrationsModelDiffer>())
.AddSingleton(db.GetService<IMigrationsAssembly>())
.AddSingleton(db.Model)
.AddSingleton(db.GetService<ICurrentDbContext>())
.AddSingleton(db.GetService<IDatabaseProvider>())
.AddSingleton<MigrationsCodeGeneratorDependencies>()
.AddSingleton<ICSharpHelper, CSharpHelper>()
.AddSingleton<CSharpMigrationOperationGeneratorDependencies>()
.AddSingleton<ICSharpMigrationOperationGenerator, CSharpMigrationOperationGenerator>()
.AddSingleton<CSharpSnapshotGeneratorDependencies>()
.AddSingleton<ICSharpSnapshotGenerator, CSharpSnapshotGenerator>()
.AddSingleton<CSharpMigrationsGeneratorDependencies>()
.AddSingleton<IMigrationsCodeGenerator, CSharpMigrationsGenerator>()
.AddSingleton<IOperationReporter>(reporter)
.AddSingleton<MigrationsScaffolderDependencies>()
.AddSingleton<ISnapshotModelProcessor, SnapshotModelProcessor>()
.AddSingleton<MigrationsScaffolder>()
.BuildServiceProvider();
var scaffolderDependencies = designTimeServices.GetRequiredService<MigrationsScaffolderDependencies>();
var modelSnapshot = scaffolderDependencies.MigrationsAssembly.ModelSnapshot;
var lastModel = scaffolderDependencies.SnapshotModelProcessor.Process(modelSnapshot?.Model);
var upOperations = scaffolderDependencies.MigrationsModelDiffer.GetDifferences(lastModel, scaffolderDependencies.Model);
var downOperations = upOperations.Any() ? scaffolderDependencies.MigrationsModelDiffer.GetDifferences(scaffolderDependencies.Model, lastModel) : new List<MigrationOperation>();
if (upOperations.Count() > 0 || downOperations.Count() > 0)
{
var scaffolder = designTimeServices.GetRequiredService<MigrationsScaffolder>();
var migration = scaffolder.ScaffoldMigration(
"MyMigration",
"MyApp.Data");
File.WriteAllText(
migration.MigrationId + migration.FileExtension,
migration.MigrationCode);
File.WriteAllText(
migration.MigrationId + ".Designer" + migration.FileExtension,
migration.MetadataCode);
File.WriteAllText(migration.SnapshotName + migration.FileExtension,
migration.SnapshotCode);
}
}
